I purchased a﻿ wet box for $6 from Walmart. then extracted all the guts out of the metal detector and install them inside of the wet box. so I can hunt in the rain and the detector can be dropped into water for a short time without hurting it…. the frame of the metal detector is made from PVC pipe making it more durable. there are two pots inside the metal detector that can be adjusted so you can increase the Dept by about an inch or two.
